Re-published to rubygems as jekyll-tagging-lite by @mehdisadeghi.
I have merged some waiting PRs and also made a change to cache the tag_cloud function's result which signifcantly increases build time (from 12s down to 5s) on my website.
Moreover, I restructed the files so one can simple add gem jekyll-tagging-lite to Gemfile and is done. No need to
requiring jekyll/tagging (was annoying for me).
For the list of changes made to the upstream see the commit history.
The instructions below remain the same, except for the gem name and the requiring part.
All the credit goes to the original authors, Arne and Jens, and other contributors. Thank you! The purpose of this fork is mainly making my own website faster. In case the upstream shows interest I'll submit a PR of my changes. However, the upstream looks stale to me (dangling PRs and not responding to issues). Again, thanks for creating jekyll-tagging!

jekyll-tagging is a Jekyll plugin, to add a tag cloud and per tag pages plus feeds to your Jekyll generated Website.
This plugin does not reinvent Jekyll's tagging feature. It just makes it easy to use. https://jekyllrb.com/docs/frontmatter/
Add space-delimited lowercase tags to FrontMatter, e.g.
author: Willow Rosenberg
tags: feminism anti-capitalism witchcraft
Install it:
gem install jekyll-tagging
Add this line to your Jekyll project's Gemfile:
group :jekyll_plugins do
gem "jekyll-tagging-lite"
end
And in your _config.yml you have to define your layout used to generate tag pages like:
tag_page_layout: tag_page
tag_page_dir: tag
This will look for _layouts/tag_page.html>, and use it to generate tag pages into the _site/tag directory.
Now you have a new filter called tag_cloud which you can use with the site object as argument in your layout to get a cloud of all your site's tags. The tags are linked to their related tag page. Furthermore, you have a tags filter which you can feed with a post or a page object to get a link list of all its tags.
You can optionally define a per tag Atom/RSS feed. In your _config.yml define the following:
tag_feed_layout: tag_feed tag_feed_dir: tag
(tag_page_dir and tag_feed_dir can have the same value.)
If your Jekyll permalink configuration is set to something other than :pretty, and you still want to have pretty tag links define the following in your _config.yml:
tag_permalink_style: pretty
Sometimes you don't want tag pages generated for certain pages. That's ok! Just add ignored_tags: [tags,to,ignore] to your _config.yml
You can attach extra data to generated tag pages by specifying tag_page_data in _config.yml (this also works for tag_feed_data). For example, you might want to exclude tag pages from being picked up by jekyll-sitemap:
tag_page_data:
sitemap: false
(Save this to _layouts/tag_page.html if using the _config.yml snippet above.)
---
layout: default
---
<h2>{{ page.tag }}</h2>
<ul>
{% for post in page.posts %}
<li><a href#"{{ post.url }}">{{ post.title }}</a> ({{ post.date | date_to_string }} | Tags: {{ post | tags }})</li>
{% endfor %}
</ul>
<div id#"tag-cloud">
{{ site | tag_cloud }}
</div>
(Save this to _layouts/tag_feed.xml if using the _config.yml snippet above.)

{% endfor %}
